We have performed further analyses of HETE triggers HETE 4043 and HETE 4044, in conjunction with a similar event (HETE 4047). We have concluded that these events are not in fact due to a previously unknown cosmic source. They are instead due to SCO-X1, in conjunction with episodes of loss of spacecraft attitude control that can occur sporadically near the daytime terminator....Full Text

At 06:41:42 UTC on March 31, 2006 HETE-2 detected a long, bright and soft event at the extreme edge of the WXM field of view....Full Text

The main peak of GRB 060124 (SWIFT trigger 178750, Fenimore et al. GCN 4586) triggered the FREGATE instrument on HETE at 16:04:09.5 UTC (57849.5 SOD) on 24 January 2006 (HETE 4012). This time is 557.7 s after the Swift trigger time. The burst occurred at an angle of about 60 degrees from the HETE boresight. The main peak is the only peak of this long GRB that was sufficiently bright...Full Text

A preliminary analysis of the WXM and FREGATE spectral data for GRB 060121 (HETE 4010) shows that the data is adequately fit by a power-law times exponential model with best-fit parameters ...Full Text

At 22:24:54.5 UTC (80694.5 SOD) on 21 January 2006 the HETE FREGATE, WXM, and SXC instruments detected event HETE 4010, a bright short/hard GRB....Full Text

The HETE FREGATE instrument detected the initial peak of GRB 051227 (Swift Trigger 174738; Barbier, et al., GCN 4397) as an untriggered event....Full Text

We have performed an analysis of the spectral lag for GRB 051211A, using FREGATE data in the 30-85 keV and 85-400 keV energy bands. We obtain a spectral lag of 0.000 +/- 0.024 seconds. This result provides strong additional evidence that GRB 051211A is a short burst [Norris, J. P., Scargle, J. D., and Bonnell, J. T. 2001, in Gamma-Ray Bursts in the Afterglow Era, ed. E. Costa, F.

At 02:50:05.4 UTC (10205.4 UT) on 11 December 2005 the HETE FREGATE, WXM, and SXC instruments detected GRB 051211(HETE 3979), a GRB....Full Text

A very bright hard short GRB triggered the Konus-Wind instrument at T0=33943.785 s UT (09:25:43.785) on November 3. It was also observed by HETE-Fregate, Mars Odyssey (GRS and HEND), RHESSI, and Swift-BAT....Full Text

At 13:36:01.47 UTC (48961.47 s UT) on 28 Oct 2005, the HETE FREGATE and WXM instruments detected event HETE 3951, a bright GRB....Full Text

We have performed a spectral analysis of the WXM and FREGATE spectral data for GRB 051022. Fitting a power-law times exponential (PLE) model jointly to the WXM and FREGATE spectral data yields a chi^2 of 185 for 139 DOF, while fitting a PLE model with absorption yields a chi^2 of 131 for 138 DOF. Fitting a Band model jointly to the WXM and FREGATE spectral data also yields a chi^2 of 131 for...Full Text

The HETE team, after reviewing the the real-time messages from HETE regarding GRB 051022(HETE 3950), believes that the SXC real-time localization of this burst is valid. As reported in GCN Notices beginning 118 seconds after the initial trigger and in GCN 4131, the SXC real-time localization can be described as a circle centered at ...Full Text

HETE Fregate, WXM, and SXC detected GRB 051022(HETE 3590) at 13:07:58 on 22 October 2005. The messages sent from the satellite in real time indicate that the burst is both valid and unusually bright....Full Text

The HETE FREGATE, WXM, and SXC instruments detected GRB 051021 (HETE 3947) at 13:21:57 UT (48117 SOD) on 21 October 2005. The WXM flight localization was first reported in a GCN Notice issued at 13:22:11 UT, which was 14s after the burst trigger....Full Text

The HETE Fregate instrument detected GRB 050922C (Swift trigger 156647; Norris et al, GCN 4013). The flight instruments did not trigger because they were processing another trigger (HETE 3934) which occurred 204 seconds earlier....Full Text

The FREGATE instrument onboard HETE also detected the Swift burst GRB 050824 (Campana, et al., GCN 3866) as an untriggered event (U11648) with a significance of 6 sigma. The direction to the burst source was about 50 degrees from the instrument boresight, placing it outside the WXM and SXC fields-of-view....Full Text
